Some Effects Of Inorganic Fluoride On Plants, Animals, And Man, Delbert A. Greenwood

Faculty Honor Lectures

~~~ in the compounds of fluorine may be traced to one or more of the following factors: ( 1) the consumption of a drinking water containing one part per million of fluorine as a soluble flouride during the period of calcification and eruption of the teeth causes a reduction in the incidence of tooth decay; however, an intake of drinking water containing more than two parts per million of fluorine causes dental fluorosis of varying degrees in man and certain animals; (2) a continuous intake of excessive amounts of fluorine as mineral supplement, in contaminated forage, or the grazing of …

A Study Of The Various Stages Of Corn Foliage And Their Scale Preventing Abilities In Sea Water Evaporators, Arthur J. Rehberger

Bachelors’ Theses

Previous work carried out at Marquette University has proved that seawater evaporator scale can be prevented if such things as dehydrated alfalfa foliage or dehydrated corn, oats, pea and grass foliage are added to the feed seawater.

The object of this work is to determine if the scale preventing ability of corn foliage varies with the maturity of the plant from which it is stripped. Also if the proven scale preventing ability of mature corn foliage changes while it is stored.

The Washita Group In The Valley Of The Trinity River, Texas: A Field Guide, Bob F. Perkins, Claude C. Albritton Jr.

Fondren Science Series

Our present understanding of Washita biostratigraphy in the north Texas area is founded upon the pioneer work of W. S. Adkins, W. M. Winton and Gayle Scott. Their work was published from about 1919 to 1932, and as is inevitable many of the outcrops studied by them are no longer accessible and several new exposures have added to our knowledge of the local biostratigraphy. It is the purpose of this field guide to acquaint geologists with those localities which are now accessible and which typify Washita stratigraphy in Tarrant and southern Denton counties.

Music And You, Adele Clark Sudlow

SDSU Extension Circulars

After you have selected the best phonograph that you can afford, preferably one with three speeds (78 rpm, 45 rpm, and 33½ rpm), you are ready to begin your home record library. Long-playing records withstand rougher treatment than do the 78's, are easier to store, and will play up to thirty-two minutes per side without interruptions. They're not literally "unbreakable," but they are tough.

Geology Of The Preston Hollow Quadrangle (Dallas, Collin, And Denton Counties, Texas), George. W. B. Hall Jr.

Field and Laboratory

Bedrock in the Preston Hollow Quadrangle consists of the upper Eagle Ford shale and the middle marl and lower chalk members of the Austin formation. The area is situated upon a gentle homocline with the beds dipping 50 to 60 feet per mile to the southeast. The Eagle Ford is principally shale with interbedded thin layers of shaly limestone and sandy shale. The Austin formation is readily divisible into a lower chalk, which is a rather hard unit, and an overlying softer marly unit. There are, however, many hard chalky beds in the marl. Many thin layers of an argillaceous …

Geology Of The Carrollton Quadrangle, Dallas And Denton Counties, Texas, Vernard Winn

Field and Laboratory

Eagle Ford shale of Upper Cretaceous age underlies the Carrollton quadrangle in Dallas and Denton counties. Exposures in the western sector of the quadrangle reveal seams of impure bentonite containing nodules of pyrite and selenite. Near the center of the quadrangle, bodies resembling dasycladacid algae are located in a silty ferruginous bed. Outcrops in the eastern part of the area contain elastic limestone beds, and at one horizon, large limestone concretions. The Elm Fork of the Trinity River bisects the quadrangle, and with the aid of its tributaries, has built terraces parallel with the river. The terraces form four distinct …

The Muscles Of The Forearm Of Necturus, Joseph P. Harris Jr.

Field and Laboratory

Little of a completely satisfactory character has been published on the arm-myology of Necturus. Mivart (1869) dissected a single specimen, and described certain of the foreleg muscles. Ribbing (1906-07) dissected two specimens, and included some notes on the foreleg of Necturus, but most of his paper deals with Siredon and other forms. Wilder (1908, 1912) presented a good account of the muscles of the foreleg, and his descriptions will here be referred to many times. Howell (1936) and Straus (1942) discussed the anatomy of the flexor muscles of the forearm of Necturus; but they were interested in the broader problems …

Clastic Limestone In The Upper Eagle Ford Shale, Dallas County, Texas, William Thomas Reid

Field and Laboratory

Flaggy strata of marine elastic limestone occur in the Eagle Ford shale at a horizon approximately 100 feet below the top of that formation in Dallas County. Anticipating the possible significance of these strata as marker beds useful in correlating the type section of the Eagle Ford here with sections exposed in other areas, a detailed description of them is given.

The Teaching Of Science, Sherwin Maeser

Faculty Honor Lectures

Like to teach! Whether with the expectant, half-frightened freshman, the senior, worried about his preparation now that . he must get out and meet competition, or the graduate student interested in new discoveries, I like to work with all of them.

I have been teaching a long time now. As has always been the case when one generation is thinking of turning over its work to the next, I am glad to have the opportunity to talk about some of the things that I consider important in this job of teaching.

The most varied and the most acute problems of …

Stratigraphy Of The Woodbine Formation In The Arlington Area, Tarrant County, Texas, Charles Fremont Dodge

Field and Laboratory

The Arlington area includes 70 square miles in eastern Tarrant County, Texas. It is bounded on the west by the meridian 97° 10' 00" W, on the east by the line between Tarrant and Dallas Counties, and on the north and south by the parallels 32° 47' 30" and 32" 40' 00" N. The area is drained by the Trinity River and its tributaries, which together form a dendritic pattern. Erosion by these streams has produced a submaturely to maturely dissected terrain with maximum local relief of 200 feet. The degree of dissection varies from north to south. In the …

The Skeleton Of The Arm Of Necturus, Joseph P. Harris Jr.

Field and Laboratory

Wilder's (1903) description of the skeleton of Necturus is the only one, to date, that is anywhere near complete. Other authors (Mivart, 1869; Ribbing, 1906-07; Howell, 1936; Straus, 1942) have noted portions of the arm-skeleton incidentally to describing various muscles. Chen (1935) described the embryonic development of the pectoral limb. All of these notes generally agree, except in a few details. Francis (1934) described the skeleton of Salamandra. For reasons to appear later, I adopt the terminology of Francis for the skeletal elements of the arm of Necturus.

A Graphic Résumé Of The Pleistocene Of Nebraska (With Notes On The Fossil Mammalian Remains), C. Bertrand Schultz, Gilbert C. Lueninghoener, W. D. Frankforter

Bulletin of the University of Nebraska State Museum (1924–2023)

I T SEEMS desirable at this time to present a graphic resume of the Nebraska Pleistocene, together with a summary of the stratigraphic sequences of the fossil vertebrates. This report is based on data taken from various publications' in addition to information gathered by the present writers during the past fifteen or more field seasons. Intensive work has been done in the past five years in connection with recovery of paleontological material in the areas where government dams are under construction (Schultz, Lueninghoener, and Frankforter, 1948; Schultz and Frankforter, 1948; Holder and Wike, 1949). The information in the present paper …

Stratigraphy Of The Woodbine And Eagle Ford, Waco Area, Texas, W. S. Adkins, Frank E. Lozo

Fondren Science Series

In the last twenty years, very little detailed stratigraphy of this area has been published. Meanwhile there have been significant advances in this field: the aims of modern stratigraphic research have been somewhat clarified; much new information pertinent to the stratigraphy of this area has been accumulated from the study of other areas; and a considerable amount of detailed information on the surface and subsurface geology of this area has come to light as a result of detailed outcrop work, extensive drilling of oil tests and water wells, and new techniques of bore-hole logging. The scope of this work is …

Geology Of The Eagle Ford Quadrangle, Dallas County, Texas, William Louis Turner

Field and Laboratory

The Eagle Ford quadrangle includes an area of 62 square miles in western Dallas County. It is bounded by the parallels 32°45'00" and 32°52'30" N, and by the meridians 96°52'30" and 97°00'00" W. The towns of Irving and Eagle Ford are in the area, as are portions of Grand Prairie and Arcadia Park. A network of paved highways and graveled roads makes most of the quadrangle readily accessible by automobile. Physiographically, this area is part of the Black Prairie, a province of low relief in which the landscape has been largely shaped by running water. West and Elm forks of …

The Status Of Beavers In The Delta Area Of The San Joaquin River, San Joaquin County, California, 1950-1951, Delbert David Cram

University of the Pacific Theses and Dissertations

The term “delta area” refers to a region roughly 40 miles long and 15 miles wide situated 65 miles east of San Francisco Bay where the San Joaquin and Sacramento Rivers join and enter Suisun Bay. The waterways in this area are fresh water from these rivers, but they are affected by the ocean tides and to some extent by the salinity of the ocean water. The rgeion ecompasses about 507,000 acres, most of which has been reclaimed for agricultural purposes by the construction of levees to contain the tides and high waters. The word “islands” is used locally to …

Origin Of The Clastic Dikes In The Rockwall Area, Texas, John Napier Monroe

Field and Laboratory

Since the first of many elastic dikes was discovered near Rockwall, Texas, in 1851, their origin has been a subject of much controversy. Various observers have attributed them to the work of ancient man, igneous activity, marine sedimentation, and upward injection from parent layers of sandstone.
